Just the very tips and edges go brown and papery while the rest of the leaf is fine. This is most common in winter with the heating on, and weeping fig prefers 50–70% humidity.
The fix
Raise humidity: group plants together, sit the pot on a tray of damp pebbles, or run a humidifier. Misting helps only briefly.
Other possible causes
Not a match? Compare the signs below to find the one you have.
Inconsistent or under-watering
How to tell
The soil dries out hard between waterings, so the tips (the last to get water) crisp first.
The fix
Water more evenly: check the soil regularly and don’t let it go completely bone dry, then soak thoroughly.
Hard-water minerals and accumulated salts
How to tell
Tips brown slowly over months despite even watering, and a white crust builds up on the soil surface or the pot rim. Hard water or fertilizer salts can leave this crust. It does not identify fluoride injury.
The fix
Switch to rainwater or distilled water, and flush the pot occasionally to wash out built-up salts.
Fertilizer burn
How to tell
Tips brown within a week or two of feeding, sometimes with a white crust on the soil surface or the pot rim. It follows feeding too often or too strong.
The fix
Flush thoroughly with plain water and feed less often, always diluted.
Too much direct sun
How to tell
Dry brown patches or scorched edges show up where strong sun hits the leaf. Weeping fig wants bright light and some direct sun.
The fix
Filter the harshest midday sun with a sheer curtain for a few weeks, then reintroduce the sunny spot gradually so the leaves can harden off.
Thrips
How to tell
Silvery patches with tiny black dots point to thrips.
The fix
Rinse the plant, cut off the worst leaves and treat in rounds, as the thrips guide explains.
